How Does Ozone Protect Commercial Ice Machines?

Ozone, you’ve heard the term, but what does is it really mean and how does ozone protect my ice machine? Ozone is essentially supercharged oxygen that has 3 atoms (O3) instead of the 2 found in normal oxygen (O2). That extra atom is created through a process called electrolysis. Ozone can also be created with the help of a UV light, as well as being formed naturally in nature by processes such as lightning strikes.

Ozone as a cleaning agent

Ozone is a strong, but natural oxidizer and disinfectant. Ozone works by destroying the cell walls of bacteria and microbes it comes in contact with, killing them. By injecting an ice machine’s incoming water line with aqueous ozone (ozone in the water itself) we are able to protect more parts of the machine. As the ozone flows through the pipes, tubes, and different mechanisms of the ice machine it continues to kill bacteria it comes in contact with. This protection continues through the entire machine and is frozen into the ice itself where it will safely off-gas which helps keep the bin walls protected as well.

Which common bacteria is Ozone effective against?

Ozone has been found effective at killing many bacteria and microbes, including, but not limited to E. coli, Legionella, Listeria, and Salmonella. The CDC has found that ozone is a safe and effective sanitation method in drinking water, effective against even some of the most resistant microorganisms.

Are there health concerns with Ozone?

According to the CDC, Ozone is a safe and effective sterilization method for beverages as long as the levels do not exceed acceptable levels. Ozone has been used in food service applications for decades and remains one of the safest and best ways to ensure customers are not ingesting harmful bacteria and virus putting them at risk for food borne illnesses.

How long does ozone protect against germs?

Aqueous ozone has a “half life” of 15 minutes at which time it returns back to its original state of H20. That said, if Aqueous Ozone is frozen into cubes, the antimicrobial support is extended to the ice bins, remote ice chest, even transport vessels! On the other hand, Gaseous ozone is is made, expires and has to be re-made. It is for this reason most Gaseous Ozone MFG’S produce ozone in a given space constantly and can not produce it on demand. Remember, Ozone is a safe and approved beverage treatment and safe for consumption in small doses.
